MACHINE FOR FILLING COMPARTMENT-FIATTRESSES.

The invention also comprises a bed, a

transverse series of spouts or the like over which the compartment tickis placed and a reciprocating filling carrier on the bed C0111? prisingupper and lower setsof Presser bars or like devices, which are separableto receive the filling material, aiid which are ar-- ranged to movethrough the spoutsand into and out of the compartments of the tick.

The invention consists in the features of .iiiiproveinent hereinaftersetforth, illustrated in the preferred form in the accompanying drawingsand more particularly pointed. out in the appended claims.

The preferred embodiment of the invention illustrated in the drawingscomprisesa table frame formedof side bars 1 supported on uprights orlegs 2 and connected by a series of transverse bars 3. As shown in thedrawings, the side bars 1 and crossbars 8 are formed of angle iron andthe ends of the cross-bars overlap and are suitably secured at their;ends to the side bars. A series of wooden cross-bars 4. on the bars 3support a floor or bed. 5 which is prefer; ably covered with a metalsheathing Upright walls 8. are arrangedat the sides of the floor or bed5 and are fastened to up right posts 9 which are secured to the endsSpecification of Letters Patent. Patented Apr, 21, 1914, Applicationfiled November 20, 1911. Serial No. 661,410.- I

spouts are formed of sheet metal and are.

preferably 'of rectangular section. The. spouts are spaced one fromanother, but-tho side walls 10 thereof are flaring at their in ner ends,as-most clearly indicated in Fig. 2. The inner flaring ends of the sidewalls 10 of each pair of adjacent spouts meet at an acute angle and arepreferably secured together toforin a series of relatively sharp of thecross-bars 3' and 4. The posts 9 at... theleft hand end of the machineextend or beveled deflectors 11 between the spouts. Theflaring sidewallsof the outside spouts overlap and are secured to the posts 9. The

sheathing 6 of the floor or bed 5 is preferably extended throughthespouts and over the bottom walls thereof, as shown in Fig. 1. Thespouts are further supported in position by across-bar 12 which extendsover and is secured-to the upper, inner end portions of the spouts andthe ends of which bar are fastened to the posts 9;

' A reciprocating carrier for the filling material is mounted upon thefloor or bed 5 and between the side walls 8. This carrier comprises alower set of bars 13 and an upper set of presser bars 14, allconnected-at their inner or right hand ends to a transverse bar orcross-head 15. The'bars 13 and 14 are upper ends of the preferablyformed of thin boards or plates bed of the machine and the lower set ofbars ed over the bed, one pair of bars will enter each of the.spouts-10.

A charge of material sufiicien tofill the entire mattress is placedwithin t is box-like body and preferably a, single bat of material isplaced therein and compressed between the upper and lower sets ofpresser bars. To facilitate the placing of the bat of material inposition, the upper bars 14 are preferably hinged, as described, to thecrosshead 15, so that the upper set of bars may be elevated andthe batof filling material placed in position upon the lower set of bars andbetween the side portions 8. For convenience in holding the set of barsin elevated position, as indicated in dotted lines 1 in Fig. 1,these'bars are provided with openand lowered upon the bat. A pair ofrollers 23 are then placed in engagement with the presser bars 14 tothereby compress thefilling material. The rollers 23 are preferablyformed of wood and provided with pintles or journals 24 at their endswhich are arranged to engage notches 25 in pairs or plates 26 secured tothe side boards 8. The rollers 23 may be readily removed b disengagingthe.

pintles 24 from the note cs 25, and thus permit the elevation of thepresser bars 14 to receive the filling material. But after the materialhas been placed in position between the sets of bars 13 and 14, therollers are replaced in the machine and act upon the upper surfaces ofthe presser bars 14, so that the latter serve to compress the'filhing'material and hold itunder pressure as it is carried into the tickingof the mattress. -The notches 25 of the plates 26 open rearwardly sothat the pintles 24 will'not be disengaged from the notches as thecarrier bars are advanced.

The filling carrier is reciprocated by a pair of endless chains 27 whichextend over sprockets 28 mounted on shafts 29 and 30 at opposite ends ofthe machine. The crossbars 4 and the bed or flooring 5 with thesheathing 6 thereon, are cut away or recessed to form narrowlongitudinal spaces for the passage of the up'perportions of the chains27, and the latter are connected to the crossbar 15 of the fillingcarrier by bolts 31. The shaft 30'is driven from an over-headcountershaft 32 through the medium of a chain 33 which passes over arela tively small sprocket 34 on the countershaft 32 y and over arelatively large sprocket 35 on the shaft 30. The shaft 32 and partsconnected thereto are driven from a second over-head shaft 36 throughthe medium of suitable reversing mechanism.

Inthe construction shown, the shaft 36'is provided with a narrow fixedpulley 37 arranged between two relatively wide, loose pulleys 38thereon, and these pulleys are connected to a wide drum pulley 39 on theshaft 32 by a crossed belt 40 and an open belt 41. A belt shifter 42 isprovided with pins 43 engaging the belts and the shifter is operated-bya lever 44. The shaft 36 constitutes the main drive shaft of the machineandthe parts are so arranged that both. belts 40 and 41 may be on theloose pulleys 38 or one on the fixed pulley 37 and the other upon one ofthe loose pulleys. By shifting the belts the filling carrier may bestarted and stopped and reciprocated in opposite directions to projectthe pairs of bars 13 and 14 through the spouts 10 and withdraw themtherefrom. I

When a hat of filling material is used, it is divided into sections asthe carrier is ad vanced by a series of rotary knives 45 mounted upon across-shaft 46. The lower portions of the knives preferably extendthrough slots 48 in the floor or bed 5 of the machine and in thesheathing thereof, and the cutter shaft 46 is preferably mounted inadjustable bearings 49. These bearings are mounted in suitableguide-ways on the upper ends of a pair of standards 50 that rise fromthe side bars 1 of the machine. Set screws 51 engage the bearings andserve to adjust the height of the shaft 46, so that the knives can beadjusted and properly positioned with reference to the bed plate of themachine and with reference to the slots 48 therein.

The knives 46 are arranged adjacent and in line with the deflectors 11between the spouts 10 and out of line with the spouts. That is to say,the knives are arranged between the paths of movement of the pairs ofcarrier bars 13 and 14 and serve to divide the bat of fillingmatcrialinto sections as the carrier is advanced. A roller 52 ispreferably arranged between the sct of knives 45 and the upper port-ionsof the spouts 10, the roller being journaled in the upper ends of theposts 9. This roller is preferably provided with a series of annulargrooves 53 within which the rotarycircular knives 45 extend. The rollerengages the upper boards 14 as the latter are advanced and assists inholding the filling material under compression. The roller also assistsin clearing the knives from the filling material. The knives and knifeshafts are driven at high speed by a comparatively large pulley 57 onthe main drive shaft 36 which is connected td a relatively small pulley58 on the knife shaft by a belt 59. The connection between the maindrive shaft 36 and the shaft 30 is such that the carrier is driven atrelatively slow speed.

In operation the ticking of the compartupper and lower faces of thespouts, and

connected by a series of bolts 55 extending between the spouts andhaving thumb screws 56 on their upper ends. The clamp bars engage theportion of the ticking adjacent the open'mouths of the compartments,while the rest of the ticking is placed over the spouts and is puckered,as indicated in Fig;

4. The filling material is placed in position by withdrawing the carriertoward the right hand end of the bed of the machine, removing therollers 93 and raising the upper bars 14. The bars 14 are then loweredand the rollers 23 replaced to hold the filling material undercompression. The drive mechanism for the, carrier is then started toadvance the carrier and project the pairs of bars 13 and let between theknives 45, below the roller 52 and through the spouts 10 into thecompartments of, the ticking. The bat of filling material is thus heldcom pressed in vertical direction and is advanced between the kniveswhich serve to divide it into sections. One section is passed by eachpair of boards 13 and 14 through one of the spouts 10 into one of thecompartments of the ticking. The separation of the sections of thefilling material is effected by the pointed or V-shaped deflectors 11between the inner ends of the spouts. These deflectors also serve tocompress the sections of filling material in lateral direction as theyare forced through the spouts. The sections of filling material are thuscompressed both vertically and horizontally, as they are forced. throughthe spouts and into the compartments of the ticking to simultaneouslyfill all of the compartments at a single advance movement. of thecompressing and feeding devices. As the material is forced intothelcompartments of the tick, the latter, of course, is progressivelydrawn oil of the spouts.- \Vhen the material is in the ticking, thecarrier is withdrawn. The

friction of the walls of the compartments, upon the material issuflicient tolmld thtv material in place, so that as the boards 13 and14; are withdrawn, the material remains in the ticking. One form ofcompartment mattress is shown in Flg. 7. In thismattress, the oppositesides "(a and b of the tick; are connected by partition walls 0 to forma series of long, narrow compartments. In stufiing the tick, it is drawnover and puckcred upon the spouts 10, with the. partition walls 0disposed in the spaces between the spouts. material carriedthereby passthrough the positioned in its compartment.

As the pairs of bars and fillingspouts into the compartments, thegreater portion of the tick is drawn off the spouts. The carrier barsare then withdrawn, as described and the filled tick is removed from themachine.

It is obvious that any suitable reversible driving mechanism can beemployed for reciprocating the filling carrier and that other changesmay be made without departure from the essentials of the invention asdefined in the claims. \Vhile the filling material is preferably placedin the machine in a pad sufficient to fill the entire mattress, it isobvious that the material .may be first divided or formed in sectionsand that .then the knives may be dispensed with.

It will be observed that as each pair of clamping boards 13. 14 passbeyond the compression feed roll 52 the respective upper and lower facesof these boargls engage the respective upper and lower inner faces ofthe spout, and these faces of the spout being flat and parallel they'serve not only to guide the boards but also to maintain the compressionon the filling material while it is passing through the spout; andfurther that by reason of the fact that these spouts have considerablelength'the'y afio-rd a sufficiently extensive support for the boards tomaintain sufficient vertical compression on each charge. until thecharge is properly It will be observed therefore that the spouts haveimportant functions other than that of serving asa support for thepuckered tick and that therefore it is within the spirit of this sincethey are confined laterally only by the side walls of the spouts, andthat further as the boards (theybeing thin and flexible) emerge from theends of the spouts the cx pansive tendency of the filling material willspring the free portions of the boardsapart and thus in a measure permitthe charge to expand vertically. This lateral spreading of the chargescannot interfere with the proper filling of the compartments since bypuckering the tick upon the spouts the charges are deposited in theextreme inner ends of their compartment-s as they emerge from the spoutsAs a. matter-of fact this lateral expansion of each charge after itemerges from its spout is greatly advantageo'us in that by the time theclamping boards are started on their. return move ments the fillingmaterial will have expanded along its side edges sufficiently to engagethe partitions of the tick with sufiicient fric- &

assisted by the springing apart of the clamping boards toward theirinner ends, thereby rendering it possible to withdraw both the top andbottom boards simultaneously and thus avoid the complication ofmechanism that would necessarily follow if the boards were withdrawnsuccessively.
